Watermark Stamp Camera is a camera app that automatically stamps date, time, location, altitude and weather onto every photo you take — no editing needed, just shoot and go. Who it's for - Travelers who want each photo to carry a GPS tag and timestamp, so you never ask "where was this taken" - Site inspectors, property managers and field workers: take a photo and it's already proof with location, elevation and time - Anyone with PDFs or photos to stamp: contracts, certificates, inspection reports — watermark them in one pass - Parents tracking baby's growth: photos automatically dated, easy to look back by month - Foodies, fitness trackers, anyone who takes lots of photos and wants them organized with metadata - Not for professional photo editing or video watermarking What you can do 1. One-tap watermarked photos Open the camera, press shutter — date, time, place and weather are stamped in real time. No post-editing, no extra step. 2. Site inspection & field proof GPS coordinates + altitude + timestamp embedded into the photo. Replace handwritten inspection logs with photos that already have all the evidence. 3. Custom stamp engine Type text, generate a Chinese-style round seal on the spot. 6 styles: official seal, company seal, date stamp, inspection seal, personal seal, fun seal. Adjust color, size, rotation and position. 4. Batch watermark (Pro) Select up to 50 photos from your camera roll, apply the same watermark to all of them at once. 5. Templates for every scene 36 scene templates (6 free + 30 Pro): travel, food, fitness, family, work check-in, weather, festivals, daily quotes. Swipe left or right in the viewfinder to switch templates on the fly. Create your own and reuse anytime. 6. Document watermark (Pro) Import a PDF or photos and stamp the whole document in one pass. Choose which pages get the watermark, then adjust position, angle, size and color with a live preview. Export each image at its original ratio — no letterbox — or merge everything into a single PDF, then save straight to your album. Keep the original document and the text stays searchable. Why Watermark Stamp Camera is different Most watermark apps just overlay text. This one has a built-in stamp engine that generates real-looking Chinese round seals — useful for inspection reports, property records and daily proof. It also watermarks documents: PDFs up to 300 pages, page ranges, tiled or single watermark. The UI is Polaroid-inspired cream paper, not a cold tech interface. Everything runs on your device, no upload, no account. Privacy first Photos never leave your device. No servers, no tracking, no sign-up required. FAQ Q: Can I watermark photos I already took? A: Yes. Pro Batch Watermark lets you pick from your camera roll and process up to 50 at once. Q: Can I watermark PDF documents? A: Yes. Document watermark (Pro) imports PDFs up to 300 pages plus photos, stamps only the pages you choose, and keeps the original text searchable when you keep the original document. Q: Does it work offline? A: Date, location and stamps work fully offline. Weather needs an internet connection. Q: Is weather available in my country? A: WeatherKit by Apple covers most regions. If unavailable, the weather option hides automatically. Q: Can I create my own templates? A: Yes. Adjust layout and fields freely, save as your personal template and reuse anytime. Q: Is this a subscription? A: No. One-time purchase, lifetime Pro access, Family Sharing supported.
